Also, spoon-feed players by having NPCs shout out instructions on how to defeat bosses:
[Assault Knights appear]
Rox: “Looks like Scarlet’s getting annoyed. Don’t forget to use your Scarlet’s Army Slaying Potion if you have any.”
[Assault Knight takes a flying leap]
Majory: “The Assault Knight is going to pull you in, dodge, now!”
[Assault Knights throw up their defensive shields]
Heal-o-Tron: Enemy-unit-has-engaged-shields. Suggest-cessation-of-condition-based-skills.
Better if said warnings appear as large flashing text in front of their screens consisting of no more than two words and an exclamation “Drink Potion!”, “Dodge Now!”, “No Conditions!”
Because players are becoming too impatient (and possibly lazy) to read a long string of text on their right.
